The novel’s synopsis provides a brief glimpse into the movie:
When rich atheist Art Wellington gets shielded from gunshots by a complete stranger, he risks it all to find out why. In his search, Art begins to experience a power he didn’t know existed from a source he refuses to acknowledge.
In another place and time, someone has suddenly died. Everyone is calling it an accident, but twenty-two years later, John Williams, the former sheriff of a small town, gets a message spray-painted across his truck that blows wide open a murder investigation in which everyone in town is now a suspect.
In a twist of events that no one can see coming, these two stories collide into a dramatic climax in which the unthinkable is revealed.
